MOOS Project Viewer is a free MS Project viewer application that allows you to open, view and print any MS Project file (MPP, MPT formats). Best thing about MOOS Project Viewer is that is can run on any Java enabled platform. This includes the three major operating systems Windows, Mac OS X and Linux. This is an ideal Free alternative to ProjectReader commercial Software which is pricy.

All it requires is that you have Java Runtime Environment on your computer which can be downloaded for free from here.

If you need just open Project file, you do not need to install any software. Just go on http://www.amiproject.com and open it in browser.
You can also share your Project file with people who do not have Microsoft Project installed. Just upload it on http://www.amiproject.com and click File/Share to get a short link you can share.

This may not work for projects that have proprietary information. The company I work for has non-disclosure agreements with everyone under the sun. I feel much more comfortable opening them on my computer alone using an application. Thanks for doing this OpenTube!

MOOS Project Viewer appears to be commercial now with 30 days trial. I’ve used OpenProj in the past that is actually a full MS project-compatible editor, but I’ve run into compatibility issues with it. Also, OpenProj has not been updated since 2008. I’ve found free RationalPlan Viewer http://www.rationalplan.com/download.php and will use it for the time being.
